Literal
Maximum 10-[counter-名] [with-で] table [object-を] can-surround-[polite-えます].
Restaurant description. 最大 ('maximum') modifies the count. ~名 is the formal/polite counter for people, used in business/hospitality contexts (as opposed to ~人 in everyday speech). 囲う ('to surround, to enclose') has an irregular relationship with 囲む ('to surround, to encircle') — here 囲える is the potential of 囲う or possibly 囲む (which would be 囲める). The intended meaning is 'can sit around.'
