Suggestions for tomorrow

I haven’t been to Scarborough for years but we are heading over for the day tomorrow (4 parents with two 4-year olds and one Nana). Any tips for what to do and where to go? Cheap/convenient parking, decent coffee/breakfast, outdoor activities (the weather isn’t going to be great!), maybe fish&chips and/or ice cream. Typical day tripper stuff I suppose but thought I’d ask those in the know! Thanks
