I've been coming here since 2015 and the consistency is amazing! The Y1. Basil Popcorn Chicken is the best chicken you'll get from any boba place ever. I also love the Mango Crystal drink.

Best Boba drinks in the area. It's a little farther than my average places but I rather pay a bit more for delivery from this place, since I don't have a car Ican order from here without having to go in public transportation and spent 1 hour+ in getting back and forth and enjoy my favorite boba drinks. 
Plus I got a very nice thermal bag that's exclusively for DoorDash deliveries.

Serving size for a $20 meal is absurd. Gyo Y70. Gyu Donburi only had a handful of thinly sliced beef and all rice. Terrible

Ordered multiple times and the food always looks like they're freshly prepared and flavor is always consistent. Portion is big. Although with the price point I expect nothing less. Their beef stir fry with fried rice can easily feed 2 people if not more. Their  musubis are all amazing as well

Wow! First I am totally impressed with the cute insulated bag, gonna keep to reuse it! 
Second is the food is always yummy with generous portion. Another surprise is when I took the pork chop one out from the bag, I didn't expect it to be that steamy hot, so I had to dash to the dinner table to unload it, which tells you about the freshness!! The coconut brisket was as hot but only that I was prepared this time, haha! Definitely will reorder soon. Lastly, the discount just made this experience even sweeter!!
