After many years I went back to O’Sullivan. It has new owners and the menu has changed a bit. Hamburgers are fresh and still delicious, chicken sandwich is a whole different thing, fried frozen breaded chicken in very dense, heavy waffles, also frozen, no fresh. I must add the onion rings were done to perfection. Prices still very affordable and the ambiance reflect that quiet and friendly neighborhood vibe OSulli had for many years and people love.

Burgers are top notch. I tried their green monstah with vegan (impossible patty). Beer cheese was amazing! Got an half and half of onion rings and french fries along with it. This place is known for their burgers and rightly so 🙂

Amazing amazing place. Please for the love of everything go here. The burger was amazing. The chicken wings were amazing. The service was amazing. The second my friend finished their beer the dude got him another one. Just so you guys know, whenever I go somewhere out to eat I almost always get a burger. This burger, is one of a kind. Amazing. Kudos to everyone in this place. Amazing

Overall Rating: Okay. Good, filling burgers but wouldn’t consider it as one of the best burgers in Boston, MA. Probably wouldn’t come back. Burgers were cooked a nice medium rare, juicy, and fresh. But it was slightly dry and wasn’t seasoned enough. Granted it was a very thick patty but the meat just wasn’t anything special. Also did not like how the menu items were slightly too simple – each burger item had maybe 2 toppings each (not including lettuce & tomato). The bun was sweet, fresh, and lightly toasted, with a slight smear of butter. Each burger comes from a side of French fries which were impressively super-thick wedges that were well salted. Crunchy on the outside and soft & pillow-y on the inside. Small tavern with limited seating. Two bathrooms – one stall for women, one for men. Service was good, polite, and attentive.

If you look at the pictures be prepared cause the burgers are exactly as big as they look in the photos. If you aren’t that hungry you can definitely share with someone. Loved the homemade fries. All of them come with LTO and fries or onion rings or half half. The burger is grilled. I order medium rare, but it came too cooked, I think that maybe is because the meat is too tall. I’ll come back for sure!

First of all, burgers are great but not as great as the original long ago… second of all, they never pick up the phone, how on earth can I order if you guys don’t pick up. I’m assuming they don’t have enough staff but either way, someone needs to answer.
