Aug'2012 "Mama Big" is located along Thanon Adunlayaram, in a shop-house in the area behind the Khon Kaen University. They serve Fusion Food and have indoor seating. They are open 7 days a week for lunch & dinner. I ordered as main-dish "Fresh Spring roll" and there were very good and a little bit spicy in the Thai way. With a sweet & sour sauce. Delicious! And as they have a photo-book with mouth-watering photos of 18 desserts I could not resist and I did order a "Crpe Suzette with Orange sauce". It was a bit too sweet for my taste but .... yummy! Together with a Iced Lemon Tea the total bill was 210 Thai baht. Good value for money, for the good food & service. Facebook : FB page of Mama Big
