About right @Yehuda57 but we can fit a few more than that.
How in the world does that amount come close to being able to support that number of eateries?
Some factors
1) The list includes grocery stores, bakeries, and delis - so it's not quite that many.
2) CH gets loads of visitors (Tishrei sees thousands, for instance).
3) many restaurants don't survive on frum locals only (izzy's, basil, etc)
