web service/ hosting, programming labor embedding it in the existing site, graphic design, SAAS fees for other bullshit make up a 10k number, which is probably inflated.

The recoup assumes an extra 25% tables filled on average, ie 25 tables vs 20 every night for 90 days. If those 5 tables filled brings in 20$ after expenses each you can easily get to 10k.

A restaurant running closer to capacity is very profitable vs running under capacity.
