Goodness...what can I say?
A restaurant is one of the highest cost and lowest profit small businesses. About 60% go out of business within 3 years, which is the time period you need to be prepared to operate in the red
at a minimum. It's about 75% at 5 years.
Initial costs are high, but can't be scamped unless you happen to walk in on a really great deal on an existing business that really
is a great deal and you were the person who got the deal. Very unlikely.
Supplier problems and employee problems are endless. Just when you think there might be a profit, it's time to renovate/reupholster/replace an expensive item--usually requiring skilled labor to do the work at top dollar.
Some decent cash flow should be going within 6 mos. of opening. If you're lucky and popular, you'll be meeting expenses a fair bit of the time. A lot of this depends on how good your manager is. A good manager will manage expenses and employees well.
Here are some sites with reasonable info for beginners (probably more than you want for the game, but a skim gives all sorts of reasons why things just aren't coming up roses.

What I'd do is roll for losses each month. Maybe on month 3 or 4 I'd throw out a special event that'd give a promising little profit--maybe a street fair in front of their location, or they happen to be on the only street in the area that doesn't lose power on a Saturday from 5 to 10pm, so everyone flocks there. But regular losses otherwise. Maybe have losses decreae a bit as time goes on, looking like there's light at the end of the tunnel.
Then slam them. See post above.
Just like real life, but much cheaper. Maybe you'll convince them to not open a restaurant IRL.
It usually only takes about 5-8 years to recover financially from restaurant ownership, so long as you don't end up in jail. But you do come away with some good recipes.
