I lived in Bangkok for 1 year, in the Wattana area (in my opinion, the best area for Expats), but now I want to share the best restaurants in the area, which I recommend to everyone who will be in the city:
1. "Omi Beef OKAKI since 1839" - This is an inexpensive cafe with a large selection of wagyu where you roast yourself. The best combination of price and quality
2. Tiengna Viennoiserie - incredible delicious breakfasts and European pastries
3. AVRA - A restaurant with Greek and Georgian cuisine. An absolute favorite is the mini khinkali with truffle sauce chicken gyros
4. MENSHO TOKYO - Best Ramen in BKK (Japanese chief who has 2 Michelin stars at his rest in San Francisco)
5. Sushiro - delicious, varied and fresh sushi is cheap - the main feature of the plate is delivered by rail
6. Sam Gyup Sal - Authentic Korean barbecue, mostly locals and Koreans. Unlimited food for 350THB with no time limit
7.Chinatown district - street cafe with Hong Kong noodles for 100THB - Super tasty (definitely a hidden gem)
