I went to My Thai today for lunch after hearing they have great lunch specials. I'm also a huge fan of Siam Terrace, and I heard it was owned by the same people. I was much less impressed with this place.
The place was pretty empty, maybe 3 or 4 tables on a Friday at noon. The wait staff was OK, but nothing to rave about. The silverware was dirty, and we had to ask for a new pair. The lunch special was 8-10 dishes to choose from + you get soup or a salad for $8.00. Not a great deal for the area in my opinion.
The salad was 3 or four pieces of lettuce, a slice of cucumber, and a slice of tomato. All in all 3 or 4 bites of food- not worth a lot if you ask me. I got the pad Thai as usual and it was good food- just as good as Siam Terrace, I'm pretty sure identical to Siam Terrace. The portion was smaller because it was lunch.
My advice: if you have time to drive to downtown Urbana, I would go to Siam Terrace, better service, and more selection on the menu.
