The late, lamented Ronnie's NY Pizza on Soi Nana was great. Covid killed it.
If you want a slice of real NY Pizza, go to SOHO on Soi 11, up near the top of the soi.
Maybe even better than Ronnie's was. It's not cheap-120 baht for a slice of cheese-but
its really good. Pala is OK, if you like the thick, bready, square slice.
