A hotel in Waltham celebrates the opening of its new in-house restaurant today, partnering with Sam Adams for a kickoff in honor of the occasion. Relish Burger Bistro is officially ready to serve hungry guests at the Westin Waltham-Boston.

Starwood Hotels & Resorts first started the restaurant in Arizona in 2012, and it has since opened other locations in its hotels, including the Westin Seattle Hotel, the Westin Maui, and now in Waltham at 70 3rd Ave.

Juan Luna, who has years of experience in hotel restaurants, serves as executive chef of Relish, cooking up menu items like the Watch City Burger (complete with bacon and topped with two fried eggs), chicken wings, homemade potato chips, and a full lineup of specialty burgers. The restaurant also offers a selection of soups, salads, and more.

Relish Burger Bistro is open Monday through Friday from 6:30 a.m. to midnight, Saturday from 7 a.m. to 1 a.m., and Sunday from 7 a.m. to midnight.
