Thai Thai Takeout is absolutely the best Thai food in Charlotte! I've never been to Thailand and certainly cannot claim myself a connoisseur in Thai cuisine, but I do consider myself somewhat a foodie. Thai Thai Takeout's pad thai is packed with awesomeness. I don't know exactly how they make it, but I can certainly taste quality fish sauce and tamarind in their pad thai. If you're used to the sweet "American-Style" pad thai that's service in most thai places, Thai Thai will be very foreign to you.
The minimum wait time is usually 25 minutes. Call ahead is the best option. I drive from Concord to pick up takeout from Thai Thai in Dilworth. So, I usually place my order just before I leave home. On busy takeout nigths like Sunday, 1 hour wait time is normal.
