I think black is fine but prices should all be one color, some are gold some are white. Your slice prices and sub prices seem low to me, have you costed everything out?
I agree with the others I like the set up not the colors though the white on black looks sharp but the orange is hard to read.
You could be capturing more repeat business with your own Text marketing club on all of your advertising, signage, print, radio etc. Once you have your customers opt in, you can send weekly announcements out and offer incentives for coming in during certain periods, being present in the store on certain days to win, promoting catering and takeout, etc. You can get 500 free cards with my company to give with your samples to get people to opt in when you sign up with us. It is very affordable, less than 3.00 per day and you get 98 out of every 100 messages read which is better than any other media. I will honor the July incentive for one more week.
