OP where you located?
Find a nice museum or something (if she's a lawyer you can put on that fake "I'm cultured" steez)
Go to Target and buy two $20 kites. Go outside and say "I know this is childish but let's just fly kites at the park and talk"...It'll look like you aren't on that

but also that you are interested in her
If it's a nighttime gig go to a place that does shared smaller plates and order a few of those instead of individual meals. Sharing food to women is "cute" and fun and you can gauge if she's full and keep costs low instead of ordering a full meal for her to waste 1/2 of it
IF none of those work...

got them Quaaludes for the low... (jk
