Gastro Deli Diner

My friend, who happens to be French, tested their Frenchness and verified that this place is 100% French. That being said,
1. Food: Awesome. we ordered 4 different dishes from the menu on a random basis and everything we got was delicious.
2. Price: It is alright. I mean, you don’t feel like you’re having a great deal out of your order but you definitely don’t like ripped off as the taste and flavour is there.
3. Service: It was pretty good, given servers were French. No offense guys but we all know how service culture is in France so I was pleasantly surprised.
I will be back!

First time having snails!!! Wow! So good! Very cool place!

Loving the true french décor, service and the fact, they are holding to the pure ‘frenchness’.
Service kind of paying, kind of not paying attention, the kind of ‘I really am not bothered’ but then your order lands on your table promptly. I love that very much!
But the food. I am not so sure… My friend’s granola looked and apparently was absolutely amazing. Fresh fruits, yoghurt, honey/​agava or so.
On the other hand, my onion soup was not so impressive. I would expect such a french staple costing £9 be heavenly, but it was just ok. My soup got the cheese in a tiny separate bowl served next to the soup and tasted of some sort of stock cubes or another undefined synthetic taste…
Chips were good. Spiced up with a salty mix rather then herbal mix was — in my opinion — old fashion and unnecessary, but still tasty with plenty of crunchy bits made me happy!

Wow this place is French. Our waitress had the requisite aloofness of the French people, dumping food and drinks on the table like we were lucky to not have to go and get it ourselves.
The food was pretty good if a little expensive. The Scallops I had were probably the biggest I’ve ever seen and served with the roe attached. They do a lot of seafood so if French Seafood is your thing, I’d check it out.

Authentically French. Went in here for lunch and got everything you would expect – dark wood, baguette, fabulous French onion soup, a perfectly dressed green salad, great espresso, surely service (including giving us the wrong change), and a large bill.
It feels a bit gritty (as others have mentioned) and if the law would allow it I could just imagine ash trays on the table.
Midnight in Paris in Clapham anyone?

This was a spare of the moment choice, as we were off to the cinema but arrived a tad early for the show. The rustic authentic feel to Gastro is definitely a huge selling point; however the prices were unexpectedly high!
I ordered the Monkfish wrapped in bacon with Spinach which was £18 and was shocked when it came with no sides, I was tempted to order some mash potato, but didn’t want to miss the first half of the film. The staff were very attentive and my meal was very filling so I can’t really complain, I will try it once more as the mussels on the menu were calling me But If I am planning to do a Starter main and dessert I better make sure I’m armed with the cash to do so haha!

Fortunately, I didn’t read these reviews before searching out this, more than once recommended, café in Clapham. Otherwise, I would have kept on the hunt for a good breakfast in the area.
Yes, it’s small and a bit gritty. Yes, the waiter was fresh from France and spoke very little English. But no, he was delightfully charming, albeit, a little forgetful, but a 10 for charming.
My husband ordered an omelette. I ordered poached eggs florentine and my son ordered the Eggs Benedict. (Someday, I want Sam to write his top 10 favorites as he orders this dish everywhere we go and I think this will make the list.)
Everything was perfectly paced to enjoy a leisurely breakfast, even down to the weather outside at our café table. For me, perfectly poached eggs, fresh spinach and light, delicate toast all bathed in a creamy hollandaise sauce.
And the coffee? Like you’d expect from a French café. Hot and strong.
Next time I’m in town, you bet I’ll detour off the main street, sidestep the locals who migrate to the local movie theater across the street and grab a table in front of Gastro.

Finally, deep-​fried Camembert that you can eat, always a test in my book. Great portion sizes and good food, simply done which is just what one wants
On a cold January Friday trudging around clapham looking for an inspired meal, it was refreshing to walk into a stylised downbeat French bistro, all warm and full of character.
The final test, for me, is the quality of the Crème Brulee and it certainly didn’t disappoint. A fine crust of burned sugar overlaid a delicate creamy custard, speckled with vanilla seeds.
Definitely, one to return to

I’ve lived in Clapham for 6 years and have been here only twice. And that might just be my lot, unless someone invites me.
It’s so very French here — the waiters, the menu, the wine… and the service. Sometimes rushed, often impatient and annoyingly forgetful — their staff are hit and miss.
The food is good, or excellent, depending what you go for. Their moules are delicious (and one of the least daring options on the menu) and the andouillette, or tripe sausage, is only for the adventurous. You really can see the arteries as you bring it to your mouth.
I walk past most evenings and the outside tables are popular in the summer — regulars supping wine and snacks. For me there are more familiar and friendly and consistent haunts in Clapham, and I’ll stick to them.
If I’m feeling Gallic, I’ll more likely head to Le Pot Lyonnais in Battersea.

Meh… sums this joint up quit nicely. I’m not impressed, wine choice was good and the wine was good but my steak was undercooked with an underwhelming sauce and my partner’s scallops were way too undercooked with sauce that turned his stomach. Since half of our duo is French, it gives a bit more validity to us saying, we’ve had better french fare in London, heck we’ve had better french fare in Clapham. For the price you are going to pay, in our opinion take that 15min walk from Clapham Common and head to Le Chardon, much better taste value for your pound!
We did like the feel of this being a crowded and busy french bistro, really we don’t mind the «fitting in to a nook» dining experience as long as the food is something equally worth it’s Parisian ambiance.

Peu mieux faire…
Le cadre n’est pas le plus représentatif du restaurant français, un peu vieux, pas des plus propres, les serveurs pas toujours agréable. En ce qui concerne la nourriture, elle reste un peu cher mais est relativement bonne et typiquement français (par exemple il faudra éviter de demander votre viande à point). Un bon point pour la patisserie et les viennoiseries du matin qui nous remémorent les bonnes boulangeries de chez nous. En résumé, un restaurant à faire une fois mais pas plus.

Gastro is a lovely place — the food is amazing and the décor very charming.
On the up side it is very authentically French, the food is delicious and the staff are friendly.
However, it gets quite busy and when I went there it took quite a while for us to be served our food, which is quite pricey for what it is.
It’s not somewhere you’d want to frequent very often as the food is very rich and I’m no millionaire, but for a romantic night out or a special occasion its great!
