Sure you can.

For example:

def menu
    loop do
        puts "1. Do something", "2. Do something else", "3. Nevermind"

        input = gets.strip

        case input
        when "1"
            puts "Did something"
        when "2"
            puts "Did something else"
        when "3"
            puts "Bye!"
            return     
        else   
            puts "Invalid option: #{input}"
        end    
    end
end

menu
