Been eating lunch at Yupha's for a few years. All delightful experiences. Wasn't into Thai food before discovering this gem.
The exceptional Kao Pad (fried rice) doesn't look or taste like your typical fried rice. The house sauce they use for Pad Pak is droolworthy. And the spring rolls are the best i've had.
If you dine-in for lunch and order a meal, you get the salad bar. Not a lot of variety (kale, cabbage, cucumber, carrot...) but it's always very fresh. Smother with the HPS (Holy Peanut Sauce) for some gustatory nirvana.
Decor is earthy and artistic. Only unintrusive, instrumental Thai music plays. On the front counter (an actual work of art btw), there's always an offering of fresh food for the Buddha. When it gets real busy (every day) watch the amazing Sam sprout a 3rd and 4th arm to keep the place running and the customers happy.
If you go for lunch, try to arrive by 11:30 because they really pak it in. Just don't get there before me.
