We've been to Mesa twice in the last year and were impressed both times.  The creativity of flavors, the excellent execution, and the service was great.  Mesa is located just off the casino floor of Caesar's and provides a good, but not great ambiance.\n\nThe flip side however is the feel is business casual versus formal, which is great for a Vegas trip where you don't want something too high brow.  Expect a full house, with plenty of noise.\n\nThe food is delicious.  We had the queso fundido, the chile relleno, a couple of sides, and a dessert I cannot recall the last time we went.  Everything was cleaned off the plate.\n\nWe felt the price was also very reasonable, relative to Vegas pricing.  Overall - for a great Mexican restaurant that will impress - we highly recommend.\n\nPS - don't expect to see Bobby.  I hear he doesn't make it here too often.
