The earl of sandwich is a classic in vegas. If you are looking for a great lunch or trying to recover from the night before, the earl is always there. This is a high quality sandwich that features excellent ingredients with fresh deli meats and artisan bread.
The classic is a great place to start which features roast beef and horseradish.
The full Montigu is my personal favorite which has roast beef and turkey.
I had their salt and vinegar chips which were not my favorite S&V chips because they lack a vinegar flavor.
The tomato soup is excellent. It is creamy without tasting overly creamy and has a taste of fresh tomatoes without an added sugar flavor. I recommend getting the croutons on the side otherwise they will likely be soggy by the time that you are eating.
Even if the line looks long, they will likely be able to get to you rather quickly. They are very efficient behind the counter.
