Think about making a reservation at a restaurant if your party is of a reasonable size. Most restaurants can accommodate up to about 25 people without too much issue.
Another idea is to host the party at a party or banquet hall. This will be a more expensive option, but it can easily accommodate more people.
Think about the guest list and keep in mind if any guests need accommodations. Be sure that wherever you choose caters to people who need certain accommodations, like wheelchairs.
