I work close to Mr. Thai, and I love their lunch special! Huge tub of food + spring roll + can of pop for $7-8. I usually can't finish it all at lunch so it also serves as dinner. All for under $10!
I've had the Chicken Pad Thai, which I really love. The flavour is addictive and makes you want to keep devouring even when you're full! I've also had the General Tso Chicken and like it a LOT, but I should admit this is the only place I've ever had it from so I have no idea if it is authentic or 'right'...it's right to me, though!
The service is quick and the place is clean. Not much more you can ask for from a 'fast food' type place.
Only downside I can think of is that the daily lunch specials are not posted anywhere, so sometimes my dish of choice would not be on special when I got there. I guess it forced me to try new things, but it would be nice to know what the specials are in advance.
