Chart of Account for nightclub, dinner and bar - and software recomendation

I'd work with one of the online systems.
Quickbooks online is well known, but turning on anything (say, budgets) gets expensive. Additionally, it can get a little complicated.

Wave, Freshbooks and Xero are all reasonable options. I generally am biased towards Xero, with one caveat in this case. If they want to manage inventory, Xero doesn't do that. There are plug-ins for it. Xero is the (imho) cleanest general ledger. Wave is "free"ish, which is nice. Freshbooks seems favored by people who send a lot of invoices.

Chart of accounts? KISS. Rent, Maint, Operating (telephone, mail, everything), payroll, food & bev, alcohol. Nothing else unless it is more than, say, 2% of your expenses. Talk to a tax preparer about the items that they will *have* to have for their return. Make sure you have separate buckets for State payroll, fed payroll, etc taxes (best to keep taxes sorted)

Cheers!

The National Restaurant Association offers a Uniform System of Accounts for Restaurants, includes a guide to preparing financial statements in standardized restaurant-specific format. Probably a good starting point, with good ideas.
