Here's something of an odd question - does spotting a misspelling of a food item on a printed menu, sandwich board, etc. outside of a restaurant at which you've never eaten ever keep you from trying it out?
I've seen several spelling errors outside various places I've never tried along my travels of late. Some I take as proofreading oversights (e.g. misspelling "gyro" as "gryo") and some really have made me wonder enough to considering something else (e.g. misspellings such as "nocchi" or "appel pie".)
