I'm sorry to rain on your parade too... but, I don't think it it fly either...
When I was a kid, myself and my friends would look forward to going to the arcades. This was because the games were so much more advanced and better than anything you could get at home. Now though... arcade games, even the new ones arn't any better than what you can get on x-box, PS2, game cube, or even close to PC games. When you go to whats left of the arcade industry around here, what you see are games where you ride a surf board, sit in a car, ride a bike, ski --- interactive stuff --- because thats the only thing the arcades can offer that you can't get at home. The stand up machines are alone and unloved apart from by people like us, and thats not a big enough target audience by a long way. I'll occasionally play a classic for kicks on the original machine, but I won't spend much money as I have it at home. Kid's just arn't interested anymore, and I don't blame them to be honest.
Again all the internet cafes around here survive mainly via one revenue stream... bookings for LAN parties, and thats become less popular as faster internet is more widespread so you can frag at home, also networking equipment is cheap and easy to use now too, groups friends can set up quick and easy LANS and game away.
You plan is to offer internet kiosks / retro games. Pretty much everyone that wants internet access has it now, those that don't have it either won't use it, or more likely can find a free location to do so at friends or at work.
Bill pay? Would you use a public terminal to pay bills online? I sure a hell wouldn't... who knows what kind of information is being monitored. Plus if people want to pay bills online they would have to have accounts set up, if they know about that then the likelyhood is that they would have internet access already. Downloads? I suppose if you were in a predominantly dial up served area that could fly for large files, but if people want downloads, then they must have a computer, and you better be offering faaaaast downloads for it to be worthwhile. Video calling? who would they call? I don't know anyone with videophones, appart from webcam stuff, and thats still a gimmick and a regular phone is better IMO.
The problem is that we here, all have great memories of the 'good old days' but it's like trying to set up a company to sell buggy whips, it's just not viable anymore.
If you look at where video games are played publically, and where they may even be making money still, it's along side other services... Dave & Busters --- food, bar, games, pool etc. Chucky Cheese, food & games.
In town here there is a largish arcade that seems to be surviving, though it is 75% interactive games, 25% old style, it is also located in a complex just off the university campus, with a theater, starbucks, 30 od resturants, music stores, movie stores and the teenagers do hang out there. I'll tell you this though, even though it is at least 5 times the floor area, it is no where near as busy in there as starbucks... thats right a $3 cup of coffee has more appeal and value.
Now what could work... maybe could be a coffee shop (and it must be hip and trendy) with a LAN/internet room and retro gaming room, but still the order of profitablity would be Coffee, LAN bookings, retro --- and you'd have to offer free internet terminals I think to get interest and probably wifi.
However thinking about it more, figuring the mall cart idea, if you offered me a good cup of coffee (and I mean expresso creations etc, not drip!) with 10 minutes of internet and/or retro gaming for $3-$4... I'd be there during the hard slogs with the GF around the mall.
