Thien is located on 3rd avenue beside Red Pepper.
For looking like a tiny joint it is long and has a large amount of seating. The servers were very friendly but we had difficulties altering our orders due to the language barrier.
I honestly didn't look over everything on the menu but there was an abundance of options from Chinese and Vietnamese food to Western dishes.
The food came quick and the portions were large. I ordered a jumbo sized vermicelli bowl with meatballs, spring rolls and shrimp. The flavour was good from all of the ingredients but the beef was bit overcooked. My brother and sister also really like their meals as well (as seen above).
I am really happy with the food here. If you work downtown or are willing to give a new Vietnamese restaurant a chance, I recommend Thien. I love when I find places where you can leave full and satisfied for under $10. If you don't believe me, Urbanspoon and my friends also agree with me!
