Buddy Burger Lab, located in Dongmen Market, is an American-style hamburger restaurant with a distinctive character. The market's environment has a local lively feel, but the restaurant itself maintains a simple and neat American style without excessive decorations, focusing entirely on the food. The overall atmosphere is relaxed and straightforward, perfectly aligning with the notion of "eating burgers should be refreshing."

The several burgers we ordered this time performed above expectations. The double beef burger is quite a genuine offering, with thick, juicy beef patties that have a noticeable fatty aroma without being greasy. The double layer enhances the meaty sensation, providing a clear sense of satisfaction with every bite, and the overall structure is stable without falling apart by the end.

The most impressive item was the classic thick-cut cheeseburger. It has a generous amount of cheese with a rich flavor, melting to envelop the beef patty, delivering a smooth and thick texture. The balance between cheese and beef is well-captured, highlighting the dairy flavor without overpowering the meat itself, making it a highly complete cheeseburger.

The side of fries was also quite commendable, crispy on the outside and soft on the inside, with the oil temperature well-controlled, avoiding any heavy greasiness, making them flavorful enough to enjoy on their own.

The pricing is also quite competitive, offering high value for both quality and portion size. This makes Buddy Burger Lab not just delicious, but also a place you'd want to return to.

Overall, Buddy Burger Lab is a restaurant that excels in the core elements of American burgers: meat aroma, cheese, texture, and portion size are all spot on. If you're looking for a place in Dongmen Market to indulge in a big burger without breaking the bank, this place comes highly recommended.
