It's not working.
The kitchen is filthy. The clown working there clearly does not know about hygeine. Can not prepare more than one thing at a time. Why have an open kitchen if everyone can see the lack of cleanliness? Clearly no cleaning done the night before and stuff is left to fester overnight. How do you know stuff is cleaned properly in the morning?
Downstairs also really dirty, esp the sink area.
Service generally very poor. If you are outside, forget about service. Obediently keep going in and out to ask the group of staff chatting at the counter for what you want (usually what they have forgotten). Delivery not worth the hassle. In O Sole Mio next door the service is excellent, why not at PG?
The managers need to start doing their jobs. There should be a manager there all the time. The place needs to be clean (especially in the morning). The kitchen needs to be scrubbed. The guy who works there needs to be shown how to keep stuff tidy.
For the most expensive sandwiches around you should get much, much better than this.
