This is one of my favourite places for thai food in the city (other than Khao San Road downtown). My family and I have consistently eaten at or picked up take-out from Thai Shann Inn every other week for over 10 years at this location and their previous one. The dishes are HUGE and SO FLAVOURFUL. The chicken satay (super garlicy, amazing peanut sauce) pad thai and mango salad (sour and just the right amount of fish sauce) are out of this world. Yes, both are fairly saucy, but my family enjoys strong, delicious flavours and sauce. Always a lot of meat unless you order something like chicken fried rice, which of course is going to be 75%+ rice.
Their fried banana dessert is amazing and they also give free oranges slices and fortune cookies (yes, these cookies don't really make sense, but I'm not complaining!) at the end of the meal. They also give you free shrimp chips and peanut sauce at the start of the meal. The prices are very affordable on top of everything, all for fresh delicious thai food.
Try this place out. Seriously. You won't regret it.
