The ACS Vostok might be worth a look. Lever machine so has the theatrics for a cafe (though that might lead to RSI claims). Some more tech than most lever machines too. Dual boilers and a PID for each group. Can be had up to a 4 group.
I'm just a home user so not sure of the requirements/limitations of cafe use.
