Dress code is casual; reservations recommended but not required; The Irish Coffee is a must, it is perfect! I had the ribeye dinner which was that nights steak special. It came with smashed red potatoes and mixed veg. It was wonderful and really hit the spot. The host and my server were fantastic, friendly, and very willing to engage their guests. They made it very easy for other guests to engage each other, as I did. Atmosphere and seating A+. I wanted to go again while I was there but ran out of time. In addition to the Irish Coffee, Tom Bergin's offers a full authentic Irish Menu. The advertising says it is the oldest Irish Restaurant in LA. For an Irish Coffee, Iced Tea, and Ribeye dinner (I brought enough home for next day) it was $40.00. A great deal in LA.
