The most notable restaurant near me, (Garden Restaurant) can't even spell its own name correctly on its expensive professionally produced menus in the restaurant, your chance of scraping good enough menu data from their web site is negligible.

I actually went to the web site just to see, and it's worse than I thought. Even their Western menu, the stuff random Westerners think is "Chinese food" is presented as JPEGs of photographs (sometimes out of focus) of the physical menu, which is itself strewn with typographical errors and mysterious annotations.

So, to get even the bad text an actual patron has in the physical restaurant you need to scrape the site, download the images, and successfully OCR from low resolution out-of-focus photographs. It's not impossible but good luck to you, and at the end the results will still be pretty unsatisfactory. "Frind pok" is actually what they wrote, they meant Fried Pork, but that's not an OCR error it's really what they paid to have printed.
