I'm currently toying with the following three concepts:
1. Snatch up a lease in a hipster part of town where the locals are used to paying for $7 cup of coffee every morning and open a small overpriced gourmet hotdog shop (selling weird hotdogs like hotdogs w kimchi etc). Get a liquor license and also sell craft beer.
2. Exactly duplicate a concept for a high-end restaurant chain in EE - I won't divulge the details, but its extremely popular in EE and its packed - the only issue I'm stumbling with is I'm not sure how the US population will react to this kind of food (its not really EE food - more middle eastern, but not typical middle eastern).
3. Start a regular coffee shop in an area with increasing gentrification and build my credibility and personal brand to gain more upfront capital for ideas #1 and #2 above.

This is advice for you if you are looking at a single one or at least a single one to start with only and don't want a massive one to start.
My partner has had a few restaurants at the same time, and has sold out of all but one which she is doing at present. Asian restaurants large Australian city.
Mid priced, and the competition here is red hot. She has done very well out of it but is a very smart lady.
My observations forget option 3. Build up your capital with your current job.
You must have a decent chef, this will cost you money but the food must be quality. There is a shortage of good chefs here.
Much easier said than done to get a good one, especially with the money the big hotel chains etc. can pay. A decent chef will be on top of purchasing supplies as well.
Kitchen hands etc. easy to get.
Leasing / start up fit outs etc. Much better to take something existing over if possible, even if stuff needs upgrading. Experienced operators can tell what isn't worth touching and what is.
Most patrons couldn't care less about some wanky fit out. As long as its comfortable, good atmosphere and stuff like heating and cooling works. Way better to spend money on the air con than some wank $500 a pop light fitting etc.
Be prepared to work long hours. Get experience and absolutely focus on the figures. Overheads so much, produce so much, wages (the big one) and profit. Just like any business. Keep a close eye on these percentages.
Re your question re how long to make reasonable money? hard one but I'd say around 24 months.
There is just nothing like experience and local knowledge. All that said like any business if you just focus on what may go wrong you end up doing nothing.
