The Observatory is one of the best Night Clubs in the Salamanca District. Dress code is important, must be neat casual, no sneakers or anything like that. But once your in its a great environment, has a lounge area, a dance floor, smoking area, VIP area. A reasonable Nightclub bar, bit more expensive then other places, but worth it for the dancing and atmosphere. Best to get in early on night like Wed, Fri and Sat. Otherwise after 11 there’s quite a big line.
