It's great to see a very chic, comfortable spot in Penn Quarter that has a happy hour that extends to 8pm and has an excellent food/drink deal. For $8, you can choose 1 each from a list of cocktails and from a list of appetizers. So for what you'd normally pay for 1 dish elsewhere, you can fill up on drinks and food at SEI. Although the food is great (I'm a fan of their Kobe hotdog: a hotdog garnished with spicy mayo, crispy onions and other toppings), there's room for improvement with their drinks. The Asian Pear Sangrs is good, but I've had another drink (which I think is temporary as it's not on their website menu) that wasn't balanced. I like the concept of cocktails mixed with interesting spices and flavors, but the taste of cinnamon overpowered other flavors in this drink. So choose cocktails wisely or just go for beer or wine. And definitely come for the food.
Pros: HH deals till 8pm, solid pan-Asian dishes
Cons: drinks could use some work
