A great spot for old-school deli treats like Montreal Smoked Meat or pickled tongue sandwiches on rye, potato salad, latkes, kreplach and knish.
As well they have a great selection of mustards to go with all the sandwiches. My personal favorite is the horseradish-mustard.
This place also does great diner-style breakfasts.
PS: If you like Caesars, Caplansky's adds an extra treat to the drink - a big, dill pickle spear! A nice change from the sad stalk of celery often plunked into them in many establishments.
