my house is in utah.
mirror lake highway is beautiful and not too far from SLC.
market street grill (there are a few of them in town) has really good food. a bit spendy, but good.
the best BBQ is pat's.
best beer selection is at the bayou. you can skip that, though, and go straight to epic and get some very very good beer. again, my house.
my .02, skip the beehive house. very overrated. sorry tabs.
there are some other good restaurants, if that is what you are after.
B to C to D is an interesting choice, on your map. longer than taking either I80 or I70. more scenic, however.
july in utah is often ~100F. not nearly the humidity of savannah, however. it is still bloody hot when it is 103F outside.
i guess you better check out temple square. it wouldn't be a trip to SLC without that. from there you should head over to the tavernacle:
The Tavernacle Social Club - Utah's Premiere Dueling Piano Bar! .
