    Sandwich Club STL Visited the Posh Nosh in downtown Clayton.Sat 11/11/2017 It was a brisk autumn Saturday around 1 pm.Parking in Clayton can be a little bit of a challenge in this location. We managed to find a spot after circling the block.The Posh Nosh has a nice New York style deli feel to it.The walls are adorned with photos of past patrons and staff.There is also a signed wall in the back full of names and praises of the customer service and good food.The menu is quite extensive and may be worth a study on-line before you arrive. If not they have a convenient paper menu on the front counter as well. Being a NY style deli you can expect such lovely delicacies like corned beef reubens on rye bread and pickles.In fact all the pickles you could ever want,every table has a jar of pickles that you can help yourself to and they are delicious. Our server was friendly and helpful,she even suggested the better option between two sandwiches for one of our more indecisive members.(it turned out to be an excellent choice). We ordered the Beef Dip with Au Jus, The Forsyth (Hot ham, roast beef, provel cheese & garlic butter on grilled Kaiser roll). The Hard Salami, The Rubin, The Club (Ham, turkey, bacon, lettuce & tomato) and The lox and cream cheese with capers.With out going into to much detail on each sandwich we found that everyone was very pleased with their order. The sandwiches although not huge were of great quality and flavor. We ordered the Kinish with gravy one meat one potato.They are delicious too. Overall we thoroughly enjoyed our visit, it was all our first time here. High praises to the Posh Nosh no wonder they have been here for 51 years. Good quality,good service great Sandwiches. For the love of sandwiches #sandwichclubstl

    First time back in 20 years. Just as good as I remember! Can't go wrong with a reuben and matzo ball soup. Best old school kosher delicatessen outside of NYC.
