I visited The Abbey on Butler Street with some colleagues for a late weekday lunch. There was no shortage of tables/seating though I am sure it gets quite busy on weekends. Our server was very friendly and attentive.
There's quite a large selection of adult beverages - I got the impression this list was rotated fairly regularly as well so there should be something for everybody. We started with two appetizers - the sriracha chicken dip and edamame hummus. Both were very tasty and certainly large enough to accommodate our party of four.
For the main course, the majority of my group had burgers. The menu (for lunch at least) doesn't have an overabundance of options, but there should be at least one or two items to suit everyone's taste. Side options include fries, pasta salad, or a side salad - a nice touch to have additional choices. The burgers were quite tasty and cooked accurately to our requested temperatures.
All in all, we had a very positive experience here. The ambiance is unique and warm. Location-wise, parking is a little easier here than on some stretches of Butler Street further down, so that's also a plus. Definitely check The Abbey out if you're looking for places to eat in Lawrenceville.
