Vegan-Friendly

Not everyone at the table eats meat, and the kitchen knows it. Ask when you call — guests report the team is genuinely accommodating.

"We got a refill on bread and fries without any extra fees nor without asking. You can also choose between fries, rice and potatoes as sides."

Shared table spread with steak, fish, fries and salads

For birthdays, family dinners and long plates passed across the table.

Steaks, fish and sides land together, family-style, so the table keeps passing plates instead of waiting on courses.

"I went there for my birthday and I can only recommend the restaurant."

A warm room, set tables, and owners who know your name.
