I must say that I have been to Katz a few times and Sarge's just once. Last night I ate Sarge's at around 2AM. The place was basically empty, with only one other patron, which I thought was great. We were seated and presented with water, coleslaw and sour/half sour pickles.
I ordered a bacon Burger which was really one of the best I have ever had in Manhattan. Very fresh meat and fresh cut fries.
Though the pastrami is what really matters. We also got a Robin, which is like a Reuben, but with Pastrami. I must say the pastrami was incredibly tender and flavorful, but was just lean enough. Was not to fatty as to make it disgusting, but had just enough fat to make it taste amazing. My last few trips to Katz, were disappointments, Not only are the prices insane, but the crowd's and fatty cuts of meat, make Kat'z less desirable.
The Robin at Sarge's was one of the best sandwiches I have ever had, let alone at 2AM on a Monday morning. The pastrami was also incredibly delicious and I must say perfect. The price and service were also respectable.
Sarge's is my new spot for late night eats in Manhattan.
