fun place and very casual. i've read the reviews and i've eaten here many times. so i will add my impressions.
rudy's is a certain kind of place. there is no other quite like it. i realize tattoos are elective body art but fail to see how their presence or absence can possibly affect one's dining experience, other than to provide an extra visual dimension of an artful nature.
on to the food. the portions are large, and i have never felt there was inadequate meat or other protein in the protein plates. their mocha drinks are some of the best. ever. anywhere. sometimes a place is worth going back to again and again for something as simple as that they serve.
everything else is a cut above average, and the prices are medium. so for value, good.
it is nearly always busy, fills up. the wait staff has to hustle. it is not a place to go and expect "great service". you go there for a fun lunch or inexpensive dinner or prettygoodbreakfast.
