I visited Z'Tejas earlier today with 14 coworkers. We made a reservation ahead of time, which was confirmed this morning when the restaurant staff called me, and the food and service were both great. We were provided with 2 servers to help things run smoothly and it worked out really well. The only issues: one server forgot to bring my coworker her drink, but she apologized and made it right immediately upon realizing it; we had just a little back and forth with the order of the checks being passed out (almost all were individual). I really can't fault the servers, though...we were 15 people and 12 of us wanted our own bill. It was fixed quickly and all with a smile and professionalism. All in all, an awesome experience!
