First of all, what cities/towns have these types of restaurants? The SF Bay Area has some of these ... and, of course, Hong Kong.
Second what is usually reliable to order and what should be avoided?
This wikipedia article says that unlike Chinese-American food which is Chinese food for Americans, Hong Kong Western food is American food for Chinese people.
Here’s a menu for a SF restaurant which, from what I’ve read is representative of these types of restaurants.
In one the above joint the menu spans Chinese, American, French, & Japanese.
So for your soupy pleasure, in addtion to the borscht, there is clam chowder Japanese ramen, French-style onion soup, noodle soup, stew & porridge.
Appetizers & snacks can include escargot, egg rolls, California rolls, chicken feet or fish balls ... among other items.
Sandwiches ... Club ... peanut butter porky bun ... spam & egg ... tuna ... etc.
There’s bento-style boxes, curries, rice plates, chow mein, chow fun, prime rib, baked chicken Portuguese, fried fish, etc.
The $4 Western or Chinese breakfast includes toast, milktea, coffee, juice or soda.
As to that borscht, in a post about a SF café Gary Soup writes ...
“HK-style places often serve a borscht that's tomato based, not beet based. This may be an import of Shanghai's "Russian" soup (luosang tang). This is a very popular comfort food with beef, tomatoes, potatoes and cabbage.”
The above place doesn’t serve ginger coke which is mentioned in the wiki article. It sounded good so I searched to see if I could make it ... turns out it is served hot ... coke boiled with ginger ... sometimes with lemon. It’s supposed to be good for colds.
Well, if in the Bay Area, here’s links to a few joints
It seems like it would avoid the value meal for cheap eats.
What is your experience with these types of restaurants?
