Guelph is surprisingly bereft of competent Chinese restos.
No, no, no! Hit The The Wok's Taste downtown. Some of the best Chinese anywhere. Seriously! I have eaten many times in Chinatown in T.O. and I am originally from Ottawa and have eaten in many Chinese restaurants in Ottawa. The Wok's Taste is awesome!
For Thai there is The Lemongrass, The Red Paypaya, Pho Bien Than and several others. Some great Indian restaurants as well. For wings it is hard to beat Turtle Jacks. Shakespeares is great all around and their wings and ribs are very good as well.
What I am missing is a great "mom and pop" pizza place. Hamilton has at least 6 amazing places. Trokaderos is probably the best pizza place in Guelph that I know of... Okay, I'll admit it... I am a bit of a "foodie"...
