My girlfriend and I went there this last Wednesday evening, and while we typically enjoy our experience at TDM, this time was less than stellar. When we ordered, there were two high-school girls working the counter, netier of which was very articulate in speaking to us(we had to ask them to repeat themselves several times). We both ordered dinners and we also asked for a order of chips and queso. The cashier asked us if we wanted to make our meals combos, thereby getting drinks at a discount. We responded that we would likt to, but she ended up charging us for them seperately. Normally, the staff is very attentive, but I would recommend that if you have trouble ordering, make sure the staff hears you and that way you avoid our fate.
