Hourly rates are here
Also - most people take bartending jobs as the tips far outstrip the hourly pay. It used to be that hourly rates for bar/waitress staff was $2.80/hr + tips (below the $5.50 standard hourly rate). That was a long time ago (90s) but you get the general gist about the importance of tips. At $15/hour for a 40-50 hour week that's only $600-750/week before taxes. Think of NYC rents and then you get an idea of the importance of tips. Also at good places - your tips are pooled and shared amongst the entire staff - front of house and kitchen. So no waiter is taking $2k home per shift in tips. For your $400 meal - 2/3 of that is simply the ingredients and the rest is for overheads.
The economics of restaurants are fascinating and it boggles my mind how people make any sort of money from it.
